What is it about?
This research article delves into the use of perovskite nanocrystals, a special type of material, to improve light emission. Perovskites have excellent properties for creating tiny structures that can manipulate light. In this study, researchers employ a straightforward method involving patterned surfaces to control and amplify the way perovskite nanocrystals emit light. This is significant because in the past, controlling light emission over large areas was challenging and expensive. However, through a novel printing process, the researchers can now efficiently arrange perovskite nanocrystals into structures that emit light in a specific direction. They achieve a remarkable 13-fold increase in light directionality, the highest recorded for perovskite-based structures. This innovation allows for the scalable production of light-manipulating devices with tunable properties, which can be used in applications like advanced light sources and devices that emit nonlinear light.
